t Claims.

The invention relates to spring mattress assemblies comprising spirals arranged in rows and secured together, the objects of the invention being to provide improved means for tying tolinks employed in connecting the spirals of the several rows.

The assembly is composed of a plurality of spirals, as Ill, II, arranged in rows, as I2, I3, which may extend either lengthwise or crosswise of the assembly. The spirals of each of these rows are secured together by means of V-shaped links I4, one of such links being attached to an end turn of each spiral, the links otadjacent spirals being looped together, as shown at la'.

To provide suitable anchorage for the ends of the indentation I6, Il.

Midway of its ends the link I4 is folded under the outwardly extended distortion I8 of the end turn of the spiral, the length of the link being such that it ls normally under slight stress from end to end.

The links associated with adjacent spirals of each row being' looped together. as indicated at I5, the several spirals are connected with sumcient rigidity to maintain their alinement while permitting an ample degree of flexibility. The links are easily applied to the spirals and con- `nected together, and are so anchored to the spiral that relative turning movement is prevented. Because of the V form of the links their arms do not come into contact with the inner turns of the spirals, which are of less diameter than the end turns,` and consequently there is no metallic clicking as the spirals are compressed.

Adjacent rows. as I2, I3, of the spirals are hooks 2| formed at'the end of the ilnal turn of thespiral II, and which engage the outstanding deformation I8 of a spiral of the adjacent row I2. This connecting means not only contributes to the maintenance of the elements in an assembly in proper position, but also prevents the possibility of the disengagement of the links I4 from the deformation I8. Furthermore, by reason of the interlocking of the apex of the link with lthe end turn of the spiral, as shown, and the attachment ofL the end of the final turn of an adjacent spiral at the point of such interlocking, such attachment is indirectly with the link, as all of the stress from the neighboring spiral is cornmunicated to it and is not borne by the spiral through. which the connection is made. It will be seen that these stresses are transmitted to the chain of which the link is a part, and thus spread over a Wide area of the spring assembly.

The spirals of one of the outer rows, as I2, or the assembly may have their end turns closed, as indicated at 22. The link loops I9 at the ends of the several rows may carry a binder helical 23.

I claim as my invention:-

1. In a spring mattress assembly, in combination, spirals arranged in rows, a terminal turn of such spirals being distorted at diametrically opposite points, such distortions of adjacent spirals being in alinement, such terminal turns having each an outwardly projecting distortion intermediate of the iirst-named distortions, a link associated with each of such terminal coils and having its ends securedl to the named oppositely disposed distortions, and its body portion looped over the named outward projection, the ends of links of adjacent spirals being looped f together.

outward projection, the ends of links ofv adf jacent spirals of the same row being looped together, the ends of the terminal turns of spirals of adjacent rows being in hooked engagement with the named outwardly projecting distortions.

3. In a spring mattress assembly, in combi- `preferably connectedtogether by means of the' nation, spirals arranged in rows, a V-shaped link associated with each spiral and being an chored to the end coil thereof at diametrically opposite points and at its apex, the ends of the links of adjacent spirals being in looped engagement, and a binder inthe form of a helical threaded into the link loops at the outer margins of end spirals of the several rows.

4. In a spring mattress assembly, in combination, spirals arranged in two sets of relatively normal rows, the spirals of one set of rows being connected by the end of the terminal turn of one with the 4terminal turn of a laterally adjacent spiral and the spirals of the other set being united by a set of interlocked V-shaped links, the terminals of each link being attached to the terminal turn of one of the spirals at opposite points on the central line of the row, and the apex of the link being attached, to the same terminal coil.

5. In a spring mattress assembly, in combination, spirals arranged in rows, a V-shaped link associated with each spiral and'being anchored to the end coil thereof at diametrically opposite points and at its apex, the ends of the 'links` of adjacent spirals being flexibly interlocked and the end terminal of laterally adjacent spirals being connected with each of the mst-mentioned spirals at the apex or the link.

6.,A spring assembly formed of spirals arranged in juxtaposedrows, the spirals of each row being; connected by a continuous chain formed of V-shaped links, each link having its ends in connected engagement with the terminal turn of one of the spirals and at opposite portions thereof, andA in eye engagement with the ends of links associated with adjacent spirals, the end of the terminal turn of each spiral being connected with the contiguous spiral of an adjacent row and thereby indirectly connected with the apex of the link associated with such spiral.

7. In aspring assembly for mattresses, spirals arranged in rows, the spirals of each row being connected by a chain formed of interlocked V-shaped links, the ends and the apex of each link being attached to an end turn oi' one of the spirals, such attachment of the link ends being on the central longitudinal line of the row of which the spiral is an element.

8. In a spring assembly for mattresses, spirals arranged in rows, the end-turns of thespirals of inner rows being attached to the end turns of spirals of an adjacent row, the spirals of .each row being connected by a'chain formed of interlocked V-shaped links, the ends and the apex one of the spirals, such attachment of the link ends being on the central longitudinal line of the row of which the spiral is an element, and binders crossing the ends of the rows and attached to the end spirals thereof. y
